  1. Re:death of the pc? on Apple Devices To Reach Parity With Windows PCs In 2014 · · Score: 3, Informative

    Sunspider score? That's more to do with improving Javascript engines than a better CPU! The Note 3's CPU is apparently capable of 930 MFLOPS, while even the lowest end E6300 Core 2 Duo can get 8.8 GFLOPS.

    If you count GPU performance then the iPhone 5s has 76.8GFlops, but then consumer graphics cards were up to 1TFlop by 2009.

    Will a Raspberry Pi running a minimal Debian (or other Linux) installation on an air-gapped network (it can even be just the Pi plugged directly into the host via a crossover cable) using an encrypted tunnel like SSH really be any less secure than a running a custom decryption service over some kind of custom USB bridge? (I assume you were thinking this, otherwise it's back to being networked anyway)

    If your host PC is compromised than nothing is going to stop it requesting decrypted data from the Pi anyway.

    ... you get to dive for the 10 minutes that the "micro-battery" can provide power?

    Seriously we go through this every time one of these artificial gills is announced, you need too high a flow rate for a battery to realistically be able to provide power for, so you end up with a system that lasts for far less time than a simple air tank could provide.

    You know what really annoys me? How almost all 1080p displays these days seem to, by default, take the hdmi video input, slightly up-scale it (to overscan) and sharpen the hell out of it.

    What the fuck?? It's a digital signal, they're taking the literally pixel perfect input and ruining it by smearing individual input pixels over several output pixels and putting sharpening artefacts everywhere. Why? When is that ever a good idea?? Why would you ever need to overscan HDMI?

    Who cares about CFLs? LED bulbs have reached price parity with CFLs while having none of CFLs major disadvantages.

    Tho having said that, I have several 8 year old CFLs in open fixtures that don't run hot and haven't dimmed noticeably either.

    Why is everyone whining about CFLs? Get decent LED bulbs, the spectrum is perfect. I did a side by side test with "very warm white" LED and halogen spotlights, you seriously can't tell the difference.

    How many solid state devices costing less than $10 and subject to heavy heat cycling do you have in your house from 1994 that still work?

    I thought you said you'd only be using this bulb once a week for 5 minutes? I've subjected some of my high-power LED spotlights to far more extreme thermal cycling than that already (in a high-humidity environment) without issue. You can't have it both ways, you can't complain that an occasional use bulb is a waste of money because it will fail with heavy use.

    On the subject of Nuclear, coal power kills more people in Europe every year (respiratory diseases) than Nuclear power has ever killed. Still, no reason to use more power than we need to.

    I'm pretty sure the UK is still in the EU (even if it doesn't like to admit it), and none of those things have happened here. I have 8 year old CFLs that work fine, and I have reasonably priced LED spotlights that are indistinguishable from the halogen spotlights they replaced.

    Take your FUD elsewhere.

    Why do you need to throw that LED bulb out after 20 years though? Just keep using it if you're worried about wasting your $10.

    That WASTES energy because it takes a lot more energy to make that CFL than the incandescent would have ever used.

    Maybe with CFLs if they degrade over time (not that I've actually ever had a CFL fail on me, even occasional use ones.) but if you pick something like an LED lightbulb then it will sit there, and you know what if you don't get your money's worth before you move out of that house you can take it with you and use it in your next house! Hell you can even pass it down to your children if you want.

    Using CFLs in such roles wastes 95% of the resources used to make them

    Then get LED bulbs, they won't degrade over time while switched off so it should last plenty long enough to make the investment worthwhile.

    it would be stupid and wasteful to throw out all our ceiling
    fans and buy entire new ones just to have a CFL capable dimmer

    You do know you can get CFL and LED bulbs that are compatible with regular dimmers right?

    Coal power plants releases more mercury to power an incandescent bulb than a CFL would over its lifetime even in all the mercury inside was released straight into the atmosphere.

    Plus there's no mandate saying you have to use CFLs, LED bulbs have now become a good alternative.

    Also, it's actually somewhat convenient because 1000 foot vertical separation for flights in opposing directions is a good distance. There's no metric equivalent that's as easy to compute, so this is a rare example of Imperial actually creating easier math instead of harder.

    Interesting point, 300m is a slightly awkward value, I wonder if 250m (~820 feet) would be enough separation with today's more accurate autopilots etc.?

Almost all other laptops you can simply buy a new one and shove it in the back, even keeping the old one as an extra to extend battery life on long trips.

    You may not agree with Apple's position that every single milimeter and ounce matters, but that position is legitimate.

    Good point, I meant to say legitimate technical reason. The batteries are already pressed firmly against the bottom of the case with foam spacers and held in place by other components (such as those air guides, or whatever they are) and adhesive strips, there is no reason to glue them to the case when a few small plastic extensions on existing components would hold them just as well.
